Answer:
This is not a proportion
Step-by-step explanation:
Set up a proportion
9/6 = 2/1
Check with cross products

9 = 12
This is not true so they are not proportional
Answer:
f=7/5x+27/5
Step-by-step explanation:
you just have to divide both sides by -5
Answer:
N - 2 r t²
x = - ------------
7x
Step-by-step explanation:
N = 2 r t² - 7 r x
solve for x
N = 2 r t² - 7 r x
N + (-2 r t²) = (2 r t² - 7 r x) + (-2 r t²)
N - 2 r t² = 2 r t² - 7 r x - 2 r t²
N - 2 r t² - 2 r t² + 2 r t² = - 7 r x
N - 2 r t² = 7 r x
therefore,
N - 2 r t²
x = - ------------
7x
